What kind of filtration do I need for my Phoenix AZ pond?
The type of filtration you need for a Phoenix AZ pond varies wildly by what type of pond you want or have. It also depends on your goals. For example, if your goal is to raise show Koi, that's a decidedly different kind of filtration and circulation system (and entire pond concept, frankly), than if you want a water garden to host pet Koi or goldfish. Fish are an integral part of a pond ecosystem, but a water garden may not be the best choice for raising show Koi.
Basically, you need both mechanical and biological filtration for any living water feature. YOU can be both of these. OR, you can install systems that do the work for you. There are MANY to choose from. Just remember that you tend to get what you pay for in life. You can purchase most equipment online these days, but that rarely comes with good customer service.
We are absolutely familiar with all styles and types of ponds -- and there are literally HUNDREDS of ways to build a "pond."
